Application filed February 16, 1912. Serial No. 677,928.

at Lansing in the county of Ingham, State of Michigan, have inventedcertain new and .useful Improvements in Rotary Internal-Combustion'Engines; and I do declare the followingto be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to the charactersof reference marked thereon, which form a part of this specification. I

This invention relates to rotary internal combustion engines, andconsists in the construction and arrangement of parts hereim after morefully set forth and pointed out particularly in the claims.

The main object of the invention is to produce a comparatively simpleand inexpensive construction of the character described whereinprovision is'made for employing vibratory sector pistons whichalternately actas abutments and as power developing factors, provisionbeing made for transmitting movement from said sectors to the eccentricshaft.

A further object is to provide for primarily compressing the explosivecharge before admitting it in to the combustion cylinder, and againcompressing said charge after introduction into the combustion cylinderprior to ignition, and a further object is to provide for cooling theengine by air.

The above objects are attained by the mechanism illustrated in theaccompanying drawings, in which Figure 1 is a horizontal section throughan engine involving my invention, the upper part of the case in which islocated the wheel on the eccentric driven shaft, the crank arms andlinks connecting the concentric shafts of the engine thereto beingremoved, and

said arms and one of the connecting links being partly-in section. Fig.2 is a vertical sectlon in a plane at right angles to Fig. 1. Fig. 3 isa transverse section through the casing and concentric shafts, as online 3-3 of Fig. 2. Fig. l is a transverse section through the engine'as on line 4-4 of Fig. 2, illustrating the position of parts at theinstant of explosion. Fig. 5 is a fragmentary spark plugs. Fig. '6 is atransverse section similar to Fig. 4 showing the position of partsimmediately following an explosion, with one of the sector pistonsmaking a power stroke, illustrating the operation of compressin a char efor a succeeding explosion, an also il ustrating the operation ofdrawing a new charge into the inner compression chamber. Fig. 7 is atransverse section similar to Fig. 4, showing a complete transpositionof. the parts from the position shown in Fig. 4, wherein the powerdeveloping sector of Fig. 4 becomes the abutment, and the abutmentsector of Fig. 4 becomes the power developing sector. Fig. 8 is atransverse section as on line 88 of Fig. 2. Fig. 9 is a side elevationof one of the piston sectors. Fig. 10 is an inverted plan thereof. Fig.11 is a front elevation of the engine with the concentric shafts insection, as on line 11-11 of Fig. 1. Fig. 12 is a side elevation of oneof the charge forming or compressing sectors working in the compressionchamber. Fig. 13 is an inverted plan thereof.

Referring to the characters of reference, 1 designates a suitablesupporting frame at the rear of which is a case 2 into which extends oneend of the driven shaft 3 carrying the fly wheel 4. Journaled in theframe is a solid shaft 5 upon which is mounted to rotate therewith acircular disk 6 having at its peri hery a laterally extending flange 7which crms the circular perimeter of the cylinder. and which is providedwith the heat radiating fins 8. Formed integral with and projectinglaterally from the inner face of the disk 6 concentric withtheperimetrical flange or wall 7 is a.circular flan e 9. Mounted torotate upon the shaft 5, an extending longitudinally thereof, is ahollow concentric shaft 10 which is suitably jour naled in the frame,and to which is fixed a circular disk 11 which represents the rear' sideof the engine as opposed to the disk 6 which represents the front sidethereof. The rear disk 11 has perimet-rical contact with the inner wallof the flange 7 of the disk 6 in a manner to allow, of a relativemovement between said disks which are held together by means of a ring12 secured to a part of the flange 7 by screw bolts 13,

35 through one end thereof.

said ring bearing against a portion of the outer face of the disk 11, asclearly shown in Figs. 1 and 2, to effect a tight closure between saidparts. Formed integral with 5 and projecting laterally from the innerface of the rear disk 11 is a circular flange 14 which is concentricwith the flange 9 and lies therein. Between the inner faces of the disks6 and 11, and between the concentric faces of the flanges 7 and 9, isformed the cylinder or combustion chamber 15 of the engine, whilebetween the inner faces of said disks, and between the circular flange14 and the hollow shaft 10 is formed the circular com-' 5 pressionchamber 16 of the engine. Upon the inner ends of the concentric shafts 5and 10 are the crank arms 17 and 18 respectively which are connected bythe respective links 19 and 20 with the diametrically 20 opposed wristpins 21 on the fly wheel 4. It

will be noted that shaft 3 carrying said fly wheel is eccentric to theconcentric shafts 5 and 10.

Bolted at 22 to the inner face of the front 5 disk 6, so as to liewithin the circular combustion chamber or cylinder, is a sector A whichin transverse section is co-extensive with the transverse area of saidcylinder, and also bolted at 23 #to the inner face of the front disk 6is a sector B which lies within the compression chamber 16 and isco-extensive therewith in transverse area.'

upon and turned in unison with the front disk 6, and also with the shaft5-with which said disk is connected. Lying within the cv'linder orcombustion chamber 15 is a sectbr C which is bolted at 26 to the innerface of the rear disk 11, and which is co-extensive in transversesection with the transverse area of said cylinder. Within thecompression chamber and bolted at 27 to the inner face of the rear disk11 is a sector I) which in transverse section is co-extensive with thetransverse area of said compression chamber. Like sector B the sector Dis provided with a chamber 28 which communicates through one end thereofwith the compression chamber, and from which leads a passage 29 openingthrough the. periphery of said sector.

It will be noted that sectors C and D together with flange 14 arecarried upon and rotated in unison with the disk 11, and also with theshaft 10 with which said disk is connected. Formed through the flange 9are the ports 30 and 31, and formed through the flange 14 are the ports32 and 33. Formed rosarsc ing with the compression chamber are theintake ports 34 and 35. Also formed through the rear disk 11 are theexhaust ports 36 and 37 which communicate with the cylinder 15. In thering 12 are the ports-36 and 37 which, by the rotation of said parts arecaused to alternately register with the ports 36 and 37 during theperiod of exhaust.

Mounted upon the frame and embracing a portion of the outer faces oftherear disk 1 and the ring 12 is a fixed disk 38 having thereon radiallydisposed heat radiating fins 39. On the rear face of the fixed disk 38is a housing 40 (see Figs. 1 and 8) having therein an exhaust chamber-41which is adapted, as the rear disk 11 revolves, to be successivelyplaced in communication with the combustion chamber or cylinder throughthe exhaust ports 36 and 37, and theports 36 and 37 in the ring 12registering therewith, the exhaust escaping from the chamber 41 of saidhousing through the port 42. (See Fig. 8.) Also formed through the fixeddisk 38 is an intake opening 43 to which may be connected a carbureter,not shown, or any other suitable source of explosive mixture, and which,as the disk 11 revolves, is made to successively communicate with theintake ports 34 and therein communicating with the compression chamber.

The sectors A and C servealternately as the power developing piston andthe abutment for said piston. Said sectors being each connectedindependently with its shaft, and said shafts being each connected bymeans of a crank and link with the fly wheel of the driven shaft. saidlast mentioned shaft is successively driven by said sectors as they arealternately brought into use as the power developing piston.

Sectors B and D serve as compression sectors through the operation ofwhich the explosive charge is initially compressed so that it may beintroduced into the explosive cylinder from the compression chamber. Themovement of the sector which effects such com ression of the chargeserving also to draw t rough the intake port at that time incommunication with the source of expl sive mixture a succeeding chargeto be subsequently compressed by the compression travel or movement ofthe succeeding sector.

At the instant a charge is exploded. to im pel a sector piston throughthe are of the cylinder the position of parts connecting said sectorwith the driven shaft is such that a long leverag is exerted by saidsector over said shaft, causing the power developing sector to describewithin the cylinder an are representing 270, while the other sectorconnected with the driven shaft is on the short end of thedever; formedby thc parts the two sectors reverse their relative move' ments, the onegoing slow during the first half making a quick movement during thesecond half, and vice versa, the vibratory movement of the sectorsandconcentric shafts turning the driven shaft at a constant velocity.

In describing the operation we will as sume that the parts are in theposition shown in Fig. 4., at which time there will be a. compressedcharge betweeirthe adjacent ends of the sectors A and C which isexploded by a spark from the spark plug 14 being one of two carried uponthe front disk 6 and communicating with the combustion chamber. Theenergy created by the exploded charge drives thesector C around thecylinder three-quarters of a turn, while the sector A which serves as anabutment for the sector C moves through the circular cylinderone-quarter of a turn to the position occupied by sector C before theinstant of explosion. This movement of sector C turns the driven shaftone-half of a revolution. The succeeding explosion which is caused bycurrent through spark plug 45 drives the sector A around the cylinderthree-quarters of the distance thereof, while sector A moves to theposition occupied by sector C; thereby completing the cycle of movementand turning the driven shaft one revolution during two explosions in thecylinder or combustion chamber. The position of parts after completingone-half of a cycle of movement from the position shown in Fig. 4 isillustrat ed in Fig. 7, while the intermediate position, afteranexplosion has impelled the sector piston C a portion of the distancewhich it travels after one impulse, is illustrated in Fig. 6.

The explosive charges which are successively admitted to the cylinder15, or explosion chamber, are formed in the chamber 16 and dischargedinto said explosion chamber in the following manner, reference beingagain had to Fig, 4 wherein we will assume the piston or sector A hasjust been impelled to the position in which it is shown by an explodedcharge, and in reaching said position has traversed three-quarters ofthe circle of the cylinder, and that sector B has moved with it. Thistravel of sector B in the compression chamber 16 not only draws intosaid chamber an explosive mixture through the ports 34 and 43 which arecaused to register while said sector B is traveling fast through thelarger arc of the cir- (:10 it describes, but also compresses the chargepreviously drawn into said compression chamber by the movement of sectorD and which is confined between the sectors B and- D, such compressedcharge being al-. lowed to escape from-between said sectors at theinstant of highest: compression when the ports 31 and 32 are broughtinto registration with the passage 25' leading from the chamber 24 inthe sector 13, allowing the compressed char e to pass into the cylinder15 and sweep irons it the burned gases -through the exhaust port 36 inthe disk'll.

the port 36 in the ring 12, and the outer exhaust port 42 in the housing40, thereby placing in the combustion chamber a charge of explosivemixture which occupies the greater are of said cylinder between thesectors A-and C. At this point in the travel or movement of the parts asucceeding explosion takes place im elling the piston or, seetorCthroughout tie greater are of the cylinder to carry with it thecompression sector D which compresses in the chamber 16 the charge drawninto it by the previous travel of the sector-B.

As the sectors C and Dare caused to move rapidly under the impulse ofthe-explosion the exhaust port 36 and port 36 in ring 12 close as wellas the intake port 43, While the port 31 is closed by the movement ofthe flange 14, as clearly shown in Fig. 6. As

43', and the charge compressed between the sectors D and B will beadmitted to the combustion chamber through the registration of the ports30 and 33 with the passage 29 leading from the chamber 28in thecompression sector D, the previously exploded charge being allowed toescape through the exhaust port :37 and port 37 in ring 12 which are atthat time open through the concurrent travel'of the rear disk 11 and thefrontdisk G-carrying said ring, It will be understood that as thesectors B and D travel with the rapidly moving pistons with which theyare connected a partial vacuum is created in the compression chamberwhich has the eifect'of creating a strong inflow of explosive mixtureare introduced into the combustion chamber, compressed and exploded, foreach cycle of movement.

The outer face of the front revolving disk 6 is provided with heatradiating fins 46 while the rear face of the ring 12' is provided withlike fins 47. The rapid rotation of the disk 6 and the ring 12 tends toradiate the heat from the surface of the fins thereof, while the travelof the fins 17 past the ends of the heat radiating fins on the fixeddisk 38 creates a draft of air from between the fins 39 which assists inexhausting the heat therefrom. The operation of drawing the explosivecharge into the central compression chamber by suction, or the creationof a partial vacuum therein, assists in cooling the engine internally.

A spark is created in the spark plugs at the proper time through themedium of a contact spring 48, shown in Fig. 5, against which a head 49on each spark plug is adapted to have frictional contact as the frontdisk carrying the spark plugs revolves, said spring being mounted on asuit able adjustable bracket 50, and having connected thereto a currentwire 51.
